CIRCLE-IRON SUPPORT.

SPECIFICATION forming part of Letters Patent No. 239,183, dated March 22, 1881.

' Application filed December21,1880. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK MUTIMER,

a citizen of the United States, residing in the city of Rockford, in the county of \Vinnebago and State of Illinois, have'invented a new and useful Circle-Iron Support, of which the following is a specification.

My invention relates to the support of circle-irons employed mainly in farm or burden wagons; and it consists in a metallic support to receive the circle-iron, and made tubular to receive a screw-bolt to fix it in position on the tongue-hounds of a wagon.

In the accompanying drawings, Figure 1 is an isometrical representation of my improved circle-iron support. Fig. 2 is avertical central section cut in the lengthwise direction of the circle. Fig. 3 is a transverse section of the shaft on dotted line as m, Fig. 2.

In the figures is represented my improved support, consisting of a tubular shaft, A, provided with a disk-like enlargement at its lower end, as represented at- B, forming a foot or base support to rest on the tongue-hounds of the wagon. The shaft A is provided, at its upper end, with a spherical enlargement, as represented at 0, through the center of which, at right angles to the axis of the shaft, is formed a hole, as atD, of proper size and form to receive the circle-iron, a portion of which is represented in place at E, Fig. 1. This support, consisting of the base, shaft, and upper enlargement, is provided with an axial opening throughoutits entire length, in three sections, differing in size and form. The'upper portion, F, of this axial opening, entering the upper end of the support and terminating, at a, at or immediately below the circle-iron, is, in this instance, circular in plan, and of a suitable diameter to freely admit the countersunk head of an ordinary countersunk screw-bolt. The bottom I) of this portion of the axial opening is formed of a countersink of proper form and size to receive the countersunk head of the bolt. Theaxial' opening G through the shaft from the bottom of this countersunk por tion, opening through its base, is of proper size and form to receive a suitable screw-bolt to connect it to the ton gue-houuds of a wagon.

At H is represented a countersunk-headed screw-bolt, of ordinary construction, threaded and provided with a screw-nut, c, in the usual manner, and is a countersunk-headed screwbolt in every particular, the same as bolts of its class found in the trade. This bolt is of proper size to freely enter the axial opening of the shaft, and its countersunk head (I- of proper size and conformation to engage the countersunk seat I).

My improved circle-iron support is preferably made of cast-iron made malleable in the usual manner of producing malleable iron parts.

In the foregoing I have described my improved circle-iron support formed with an axial opening circular in cross-section, and a conical or countersunk seat for the bolt-head, all of which Iprefer; but otherof the known forms of openings and of screw-bolts differing in crosssection and provided with different formed heads may be employed, and still be within the scope of myinvention, so long as the support is provided with an axial bolt with which to fix it in position on the wagon to support the circle-iron.

As will be seen at Fig.3, I have formed the shaft of my improved support with fluted sides, by which construction I attain great strength with a small amount of material, and such construction insures a better article of malleable iron.

By this construction I utilize the full strength of the bolt, its strength not being in the least impaired by its connection with the support.

I claim-as my invention The combination, with the base or foot support provided with a hole for the insertion of a circle-iron and a hole extending longitudinally through said support, ofa fastening-bolt having its head fitted in a recess formed beneath the opening for the circle-iron, substantially as set forth.

FREDERIO K MUTIMER.
